As to the smell, for now I finished my prototype filter, and I'm calling it a moderate success, as proof of concept, it works. Howeer I hae a feeling I'm going to hae to inest in an inline duct fan for extra blowing power, PC fans are great for circulating but not for creating air pressure differences. Will ealuate during next few days, if there's a real improement with just the prototype I'll add a duplicate as originally planned, if not I'll go with the upsized model. Also, my \/ key appears to be broken, sorry about all the typos.
Here's the current prototype fan, the doubled PC fan I built earlier in my journal. I let it grab a piece of paper to confirm suction present.
Actiated carbon filter specifically for odor control. Unused portion sealed and stored. $20 got me enough material to make 6 or 7 of my filter units, which I am quite happy to call final-design stage. Only power of fan and ducting solutions are under reiew.
Salaged plastic pickle jar, added about 200 holes with my drill. Wrapped in carbon filter tightly using \/elcro that came with it and zip-ties.
I cut a hole through the lid, hot-glued some thin tough foam-rubber I had left from a screen repair (it's called spline if you want to get technical) to the outside of the lid to make a firm seal, the screwed the lid tightly to the box oer the exhaust outlet.
Then screw the jar, upside down, into the now secured lid. I used this jar/lid configuration to make filter replacement easier. Just unscrew jar, remoe used filter, wrap and secure new filter material, screw jar back on and done.
Plastic bag oer top of the assembly to check airflow, bag filled and tented, good breeze coming out.
Mission accomplished, prototype built and installed.

And it's so cool that you've made all your own stuff. Wish I could do that!
